.To all whomz't may concemf.

Be it known that I, CHARLES N. TUCKER,

a citizen of the United States, residing at New Bedford, in the county-of Bristol and State of Massachusetts, have invented certain. new and useful Improvements in Picker-Stick Check Motions, of which the v following is a specification, reference being had to the accompany ng drawings.

looms, and particularly to a picker stick check. y

The general object of my invention is to provide an improved check which is particution of this characterso constructed as to provide a frictional surface carried by the laybeam and with which, the member carried onthe picker ,stick engages when the picker stick is retracted. I

And a further object is to provide a device ofthis character which will keep the picker stick from splitting.

And, another object is to provide a device of, this character which can be put on or taken off in afew minutes and which may be laced on either'e'nd of the lay and which 7 isreadily adjustable. o

Other objects will appear in the course of the following description.

a My invention is illustrated in the accom-f v panying drawings, whe1'ein,: k v o Figure 1 is a. fragmentary s1de elevation of the laybeam of a loom, the picker stick .tlie1'e0f and my picker stick check applied thereto;

Figure 2 is of the .laybeam andpicker stick with my improvement applied; i .Figurefiis a sectional v1ew through the picker stick and the supporting bracket 12,

the check being illustratedin plan. Referring to these drawings, 10 designates the. laybeamof the loom and 11 the I picker stick thereof. The picker stick and; laybeam may be of any'suitablecharacter and the picker .stick operated in the usual manner. Theparticular construction of the laybeam and picker stick has nothing to do I withmy invention.

, My improved picker. stick check consists of two parts, one of which ismounted upon This invention relates to improvements in H a fragmentary end elevation thelaybeam of the loomand the other upon the picker stick. The. part mounted upon the'laybeamof the loom comprises a downing disposed preferably all in one plane. 1

The upper end of this bracket is formed with slot 13 which extends, when the bracket'is applied, approximately parallel to the upper face of the lay and the lower end of this bracket is formed with a rectangular notch 14. Mounted upon this bracket, as by means of the screw 15, bolt or like device, is a strip of metal, designated generally 16, which is bent to form a base 17 engaging! upon the outer face of the lower end of the bracket and" through which the screw 15 and then longitudinally, as'atlS, and riveted to the inner extremity of this portion 1Sis a strip of thin. metal 19 hrving rearpasses, the metal being then bent laterally block 22 which is designed to bear against the outer face of the picker stick. A bolt 23 passes through the arms orears of the yoke and through this wooden block and holdsthe block in'position. t o

Attached to the yoke :21 is an upwardly extending, loop-shaped member 24. The

loop; ofthis ine'mber is rectangular in form and the two opposing faces of the loopare lined internally with strips of, leather 25.

The material of the loop is ektended downward, as at 26, to formafshank which is inserted between the yoke 21 and the picker stick and is held in engagement with the yokeby a rivet 2-7.1 The opposing faces of i the loop 2%. are spaced'from eachother distance slightly less than the spaces between the outer faces of the divergent arms 1 of member 19, and in the operation of this. 'ClQ-YlCG, when the picker stick moves out x ward,.the relatively narrow end of the check member 16 will enter the loop and the loop will, moveoutward, gradually pressing the I spring arms 19 toward the portion 18.

retracted.

" running conditions. The parts from which purposes can be utilized.

Thus it will be seen that the arms 20 to gether form a yielding male member-upon which the loop 2a or female member is impaled to check the'picker stick in its out. ward movement. This checking action w ll be gradual and frictional in character. By reason of the elongated slot 13, the arm 12 or bracket may be adjusted longitudinally plied to either end of the laybeam or to both ends of the laybeam as may be desired,

and that the yoke 21 keeps the picker stick from. splittingat the point where the yoke is applied. The block 22, which is prefer-j ably of wood, keeps the yoke snug against the picker-stick so that it will not get loose while the stick is thrown. The adjustability of the partsladds very greatly to the value of this device, as by its means the device may be applied to agreat many different, forms of looms and at any time adjusted to suit the check are made. are relatively few and easily procured, while in making thestraps which form the frictional surface of the check, any scraps of leather strap such as are commonly used in looms for various It will be seen u that no oiling is required for this device,

that there is nothing to break or get out of order, and that the check is so constructed as to be thoroughly effective in practice,

and a checking member carried by the lay- V beam and having two outwardly divergent portions, each of said portions being resilient and compressible toward the other v end of the portion, said portions being adapted to be engaged by said loop-like member and the resilient portions forced inward upon the outward movement of the picker stick,

4. A picker stick checkfor looms comprising-a bracket "adapted to be applied to thelaybeam of the loom, a check mounted upon the bracket and comprising two connected portions converging toward the middle of the loom and diverging toward the outer end of the beam, each of said portions being resilient and both of said portions being faced with frictional material, and a looplike memberadapted to be clamped upon the picker stick of the loom and having parallel, vertically extending portions" covered on their inner faces with frictional material and adapted to receive said "first named portions carried by the bracket.

8. A picker stick check for looms having, in combination, relatively movable male and female members, the former being resilient and elastic and adapted to receive the latter as the picker stick is retracted to check the outward motion of the picker stick.

9. A picker stick check for looms having, in combination, a yielding and elastic male member connected to the loom frame and a rigid female member connected with the picker stick and adapted to be impaled upon the male member to check the outward movement of the picker stick.
